Unlike season 2021 when apart from Wigan and maybe us, played more games than the rest and most of them over here.

Was that a case of Catalan not playing games or their opposition refusing to travel to France.
Also, Leigh won a massive 2 games all season, are you suggesting that they should have remained in SL with a massive 4 points

It’ll be interesting to see how it’s policed should there be travel restrictions between here and France.

It's unlikely there would be restrictions now. But I'm sure the criteria to travel could change. Like Vaxing or isolation periods.
It's certainly going to be interesting.

I am looking forward to Catalan v Toulouse though. That's going to be a big event.

Season 2020 Toronto went bust, nobody went down. Catalan played 13 and won 8 games, more than Huddersfield (7), Wakefield (5), Hull KR (3), Castleford (6), they would still have stayed up even if they had forfeited games.
Season 2021 Catalan played more (23 games) than both Saints and Warrington (2nd & 3rd) (both played 21) Leigh won 2 games

Team's forfeiting games is valid if they can't prove they've done everything possible to field a team, the difficulty is team's like Salford who usually have small squad and are without reserves and academy teams, they are likely to call games off quicker than others.
